I am curious on what others are doing to preserve DVD's. It seems the only way to preserve all the content is to save the disk image. If you extract the video you have potential to loose the menu interactivity.
We use the Millenniata M-Discs as a replacement for CDs and DVDs. We burn new content on the M-Discs, as well as using them when we are reformatting old CDs and DVDs.
